Application filed March 8, '19.19. Serial No. 281,341.

To @ZZ whom t vmay concern i' Be it known that l, HARRY O, Bienne a citizen of the United liltates, residing' at ljetroit, county of lllayneJ State ol h'liehn gain have invented a certain new and ilsel'nl lniprovelinent in lllaehines for (lasting llate-(llass, and declare the YlolloWing to be afnll, clear7 and enact description ol the Figure l is an elevation pai-tlv in eeetion of devine.

Fig'. 2- is a Seotional view of the apparatus For regulating the discharge and i'nalzinggj'it antoniatieellv intermittent.

ll'igi'. is l'a Cross section ol one el the plateiis and the manner in whieli the glass is held therein.

T he nieehaniem for accomplishing this result consists of vate or platone of refractory materia l (l (l hinged together :itg and passing around carrying rollers or drums H lll Whieh are driven by mechanism not shown' and which ie not of itself any part of niv invention lint vvhieh is eoinni'on in, the art. rl`he plntene form in endless chain of platens and when they are brought under the deliver)7 receptacle they lift the valve F bv means olf' an arni l which terminates in it roller l( and which is lifted by a projection L upon each platen to open the oriee ll and zilloivxa certain amount of molten glass to llow into each platen (ins it passes under the vat C. ilhen sullieient glass has flowed into each of the platens G, the 'flap valve lf is allowed to descend and stop a further flow until it is elevated airain h v the succeeding projection upon the next platen that in turno is filled also. The valve l is hinged at lV. A plate M when a vat comes under it is al loivell 'to descend at the proper instant and Squeeze and push the molten gli into uniforni thickness in the platen Where it is thereafter Cooled. rl`he travel et the platone iS intermittent to permit the action of the plate lint is interrupted only momentarily. The ineelninisin for driving and causing this inlei'inittent action heine' old and not a part o' niv invention l do not deem it necessary i. )e it. ln the bottoni ol each platen i eorner thereof there a elidin'igi holt i i enlarged head N". The opposite oi these holte come in oontaet with a hase Q, tle holte are lifted against the tension ol epi-inge V Y and in liftiner they carry up the plete ol :fi-leeg '-,vhieh is already Cooled, in the position shown in l, at 0,. ln thisy manner the glass is elevated above 'they platen in which it is formed and can be laken oil' (lepoeitod h v en v convenientineane. The plate lil may he reeiproeated by a hand ll en one o the driven Wheels and the notion is only momentary (lne to the A iehefl to the hand wheel it (loefJ llv interfere or at least onlyl inoinentaiiljf with the niovenient olf the platen ne hand nnen the drivingr wheels ll.

The lileili valve ,lF lf ntrolled liv a spring l whieh forcee it down againet the plonger ,l and elastlealljf iesiets its lifting' h v that plunger. 'it hara` enllieient 'Foi-ee so that the valve l? Closes oil the stream of molten glass in the vet or receptacle (l in paesino over the joints of the endless hand of receptacles G (l1 l gas jet ll is provided Whereliythe glass on its delivery from said receptacle may be kept hot and plastic so as to flow easily and prevent chilling as itis delivered into the receptacles G;

The modo of operation of .this device is sufficiently understandable from the foregoing description.

That I desire to claim is:

' 1. In combination with a reservoir adapted to contain molten glass, a discharge passageway leading from said reservoir, a chain-like series of platens adapted to receive glass from such discharge passageway, meansvfor bringing each platen in place to receive glass, a flap valveclosiiigthe discharge passageway opened by each pla-ten successively as the same is brought into receiving position, means for closing said flap valve after such platen has passed from its receiving position, and a tamping plate. adapted to be brought into contact with the glass carried in each platen leveling and smoothing the saine.

2. ln combination wth a molten glass reservoir, a ilisch-arge passageway from such reservoir, Ya chain-like series of platens7 I the time such receptacle is positioned theremeans for bringing such platens successively in position to receive glass from such discharge passageway, a flap valve normally closing such passageway, means for opening" such valveby the positioning of each`platen cation.

to receive glass, a leveling plate positioned above the .run-way of traveling platens, nieans for automatically bringing such leveling plate in contact with the glass in each platen as the platen passes underneath such plate` and means for elevating the glass vout of such platen.

3. In combination with a reservoir adapted to contain molten glass and provided with a discharge passageway, a valve noi"l mally closing such passageway, a chain-like series ofglass-receptacles adapted to pass successively underneath such discharge passageway and provided with means adapted to co-act with means carried by said valve to open the saine during the time each receptacle is passing thereunder, a leveling plate vpositioned above the path of travel of said series of receptacles, a shelf spaced vertically roni said leveling-platepositioned iinderneatli saidA chain-like series of traveling receptacles in such a. manner that each ieceptacle will ride ,thereon as it passes underneatli the leveling plate, means for bringing 'said plate automatically into contact with the glass carried in said receptacle during under.

In testimony whereof, Isign this specifi- HARRY o. Bisi'siNo.
